Workarounds

  1. 90% success 
    from fastapi import UploadFile\[email protected]('/upload')\nasync def upload(file: UploadFile):\n    content = await file.read()\n    if len(content) > 1048576:\n        raise HTTPException(413, 'File too large')\n    return {'size': len(content)}
  2. 70% success 
    uvicorn --limit-max-requests 100 --limit-concurrency 10

Dead Ends

Common approaches that don't work:

  1. 90% fail

    可能导致服务器内存耗尽。

  2. 40% fail

    无法控制所有客户端。
